COMPANY, OF \VILMINGTON, DELAWARE, A CORPORA- OLIVER- FARM EQUIPMENT Tron OFYDELAWARE p I I nnivn MEANS non Application filed its 11, I The present invention relates to driv;

similar agricultural devices.

Among the objects of the-invention 18 to .provide' a novel drivemeans or mechanism for, corn harvester and the like; a drlve device that will be smooth in running, self contained, simple in construction, capable of delivering power directly, efficiently and economically, rigid and strong in' construction, vibrationless, economical in cost and opera- -tion, requiring little or no care, conveniently located for access, as for oiling, readily assembled as a unit, and subject to little or no wear. i

Another object of the invention is to centralize the power transmitting elements, from which may extend the transmission lines to the various parts or mechanisms on theharvester, and to the power source. This is preferably accomplished by arranging a group or 1 cluster of transmitting elements together, as

in a housing rigid with a given p'artof the frame "of the harvester, such as the chassis members thereof, and locating the same at a point orlocus where distribution of power may be readily effected in the various directions above stated. By havinga housing, which is preferably a single integral piece or unit, all the transmitting members may be protected and oiled, by running in a common oil or grease mass. Moreover, it is preferable to construct the housing with bearings, such as roller bearings, forthe proper operative supporting of the line elements, such as the shafts connected to the operated means i and from a part of the power transmitting means, all the bearings being thus grouped together or centralized for'the benefitsand advantages above mentioned.

' Other objects,advantages, capabilities and features are comprehended by the invention as will later appear and are inherently possessed thereby.

Referringmore in detail to the drawings,

the embodiment of the invention selected to illustrate it, is shown in connection Witha tractor operated corn harvester'comprising a tractor 1 having fastened thereto a frame" 2 connected atits rear end to the frame of the corn harvester generally designated. by

the reference character 3 inFig. 2 of the drawings. Thecorn 'harvesterhas a frame or chassis comprising a pair of'angle' members 4 and 5 extending forwardly and downwardly forming inclined portions 6 and. a.

At the rear end of the harvester is provided a suitable husking device 13 adapted to receive gathered ears of corn byway of the chute 14, connected to a conveyer mechanism .15 having a conveying chain or the like .16. In the throat of the harvester is provideda "pair of snapping rolls17 and :18.

The power mechanism operating ous parts of the harvester, such as the gathering chains, the snapping rolls, husking dethe variviceand conveyer,.receives its power froma power take-0E device carried by the tractor.

The power take-off device isto the side of.

the tractor and has a suitable gear casing 19 from which proceeds a driving shaft 2O, op-

crating a universal joint or coupling 21, connected to a shaft "22 (see Fig. 5), operativ'ely supported in roller bearings 23 in a journal box 24 rigidly secu'red'by way of fixture 25 to a frame part 6 of-the'harveste'r, as by means of rivets, bolts or the like 27, 'allas clearly shown in Fig. 5. To the shaft 22'is secured a hub plate 28 by meansof a cross pin 29, and to the rim 30 of the plate is se- Cured a sprocket wheel 31, by means of bolts 32,all as clearly shown in Fig. of the ably supported in roller bearings 38 havingQa drawings. Over the sprocket wheel 31 0perates a chain 33 leading to a sprocket wheel 34, secured to a shaft 35 by way ofacross pin 36 andakey 37-, theshaft-35being rotat- ,j ou rnal 130x39, either rigid with or an in- V tegrjal, part of a gear housingqasclearly assembly of the parts.

Upon the chassis members]: and 5 ofthe harvester, is rigidly secured a saddle or supor integrally formed a pedestal 4 1 forming an integral part of the housingtO. It w1ll r be noted that this support is located at a cona shaft 82 leading to a second joint 83 and operatingth'rough gears 84 and 85 connected to suitable mechanism for-operating the conveyer chain-16.v The'conveyer chain 16 is adapted forconveying the ears of corn to the upper part of the machine for feeding the same .by way of the chute 14 into the husker llpon theshaft 52 ispalso secureda gear 86 by means of a,key ;87.1 L'lhis gear-ji86 is in mesh witha gear 88 secured to theend of .a shaft 89' by, ineans of across pin 90 and a key 91.
